FIELD OF THE INVENTION

The present application relates to anti-foam compositions and methods ofmaking and using such compositions as well as consumer products thatcomprise such compositions and the use of same.

PARTIES TO A JOINT RESEARCH AGREEMENT

This application is a result of activities undertaken within the scopeof a joint research agreement between Shin-Etsu Chemical Co., Ltd. andProctor & Gamble Co. that was in effect on or before the date theresearch leading to the application was made.

BACKGROUND OF THE INVENTION

Cleaning and/or treatment compositions may employ materials that producesuds. In certain cleaning and/or treatment compositions, the level ofsuds is higher than desired. One manner of reducing suds is to add anantifoamer to the cleaning and/or treatment composition. Unfortunately,while antifoam compositions that comprise high viscosity silicones arehighly effective, such compositions must be emulsified before they areincorporated into a consumer product such as a cleaning and/or treatmentcomposition. In order to avoid the emulsification step, low viscositysilicones have been employed in anti-foam compositions. Unfortunatelysuch antifoam compositions are not very effective antifoams. As aresult, dilutants have been used in combination with the high viscositysilicones. Such dilutants dramatically increase the viscosity of thesubject antifoams, reduce the viscosity and the effectiveness of theantifoams, or have other negative interactions with the anti-foam'scomponents.

Applicants recognized that the problems associated with using suchdilutants, arises either from the dilutant's insolubility in thesilicone component or if the dilutant is soluble in such siliconecomponent the drop in viscosity which results in a decrease in theantifoam's effectiveness. Thus Applicants recognized that what is neededis an antifoam composition that comprises a dilutant that lowers theviscosity of the neat anti-foam and when the antifoam is mixed with aconsumer product migrates from the antifoam into the consumer product.In short, the antifoam compositions disclosed herein have lowviscosities yet provide the desired antifoaming efficacy.

SUMMARY OF THE INVENTION

The present application relates to anti-foam compositions and methods ofmaking and using such compositions as well as consumer products thatcomprise such compositions and the use of same. Such anti-foamcompositions have low viscosities yet are effective antifoamers.

Fillers and Carriers

Fillers and carriers may be used in the cleaning compositions describedherein. As used herein, the terms “filler” and “carrier” have the samemeaning and can be used interchangeably.

Liquid cleaning compositions and other forms of cleaning compositionsthat include a liquid component (such as liquid-containing unit dosecleaning compositions) may contain water and other solvents as fillersor carriers. Suitable solvents also include lipophilic fluids, includingsiloxanes, other silicones, hydrocarbons, glycol ethers, glycerinederivatives such as glycerine ethers, perfluorinated amines,perfluorinated and hydrofluoroether solvents, low-volatilitynonfluorinated organic solvents, diol solvents, and mixtures thereof.

Low molecular weight primary or secondary alcohols exemplified bymethanol, ethanol, propanol, and isopropanol are suitable. Monohydricalcohols may be used in some examples for solubilizing surfactants, andpolyols such as those containing from 2 to about 6 carbon atoms and from2 to about 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol,glycerine, and 1,2-propanediol) may also be used. Amine-containingsolvents, such as monoethanolamine, diethanolamine and triethanolamine,may also be used.

The cleaning compositions may contain from about 5% to about 90%, and insome examples, from about 10% to about 50%, by weight of thecomposition, of such carriers. For compact or super-compact heavy dutyliquid or other forms of cleaning compositions, the use of water may belower than about 40% by weight of the composition, or lower than about20%, or lower than about 5%, or less than about 4% free water, or lessthan about 3% free water, or less than about 2% free water, orsubstantially free of free water (i.e., anhydrous).

For powder or bar cleaning compositions, or forms that include a solidor powder component (such as powder-containing unit dose cleaningcomposition), suitable fillers may include, but are not limited to,sodium sulfate, sodium chloride, clay, or other inert solid ingredients.Fillers may also include biomass or decolorized biomass. Fillers ingranular, bar, or other solid cleaning compositions may comprise lessthan about 80% by weight of the cleaning composition, and in someexamples, less than about 50% by weight of the cleaning composition.Compact or supercompact powder or solid cleaning compositions maycomprise less than about 40% filler by weight of the cleaningcomposition, or less than about 20%, or less than about 10%.

For either compacted or supercompacted liquid or powder cleaningcompositions, or other forms, the level of liquid or solid filler in theproduct may be reduced, such that either the same amount of activechemistry is delivered to the wash liquor as compared to noncompactedcleaning compositions, or in some examples, the cleaning composition ismore efficient such that less active chemistry is delivered to the washliquor as compared to noncompacted compositions. For example, the washliquor may be formed by contacting the cleaning composition to water insuch an amount so that the concentration of cleaning composition in thewash liquor is from above 0 g/l to 6 g/l. In some examples, theconcentration may be from about 0.5 g/l to about 5 g/l, or to about 3.0g/l, or to about 2.5 g/l, or to about 2.0 g/l, or to about 1.5 g/l, orfrom about 0 g/l to about 1.0 g/l, or from about 0 g/l to about 0.5 g/l.These dosages are not intended to be limiting, and other dosages may beused that will be apparent to those of ordinary skill in the art.

Buffer System

The cleaning compositions described herein may be formulated such that,during use in aqueous cleaning operations, the wash water will have a pHof between about 7.0 and about 12, and in some examples, between about7.0 and about 11. Techniques for controlling pH at recommended usagelevels include the use of buffers, alkalis, or acids, and are well knownto those skilled in the art. These include, but are not limited to, theuse of sodium carbonate, citric acid or sodium citrate, lactic acid orlactate, monoethanol amine or other amines, boric acid or borates, andother pH-adjusting compounds well known in the art.

The cleaning compositions herein may comprise dynamic in-wash pHprofiles. Such cleaning compositions may use wax-covered citric acidparticles in conjunction with other pH control agents such that (i)about 3 minutes after contact with water, the pH of the wash liquor isgreater than 10; (ii) about 10 minutes after contact with water, the pHof the wash liquor is less than 9.5; (iii) about 20 minutes aftercontact with water, the pH of the wash liquor is less than 9.0; and (iv)optionally, wherein, the equilibrium pH of the wash liquor is in therange of from about 7.0 to about 8.5.

UV Absorbers—in certain consumer product embodiments of the presentinvention, the photo-responsive encapsulates of the present inventionmay be stabilized against premature release by exposure to light of asufficient wavelength during storage by incorporation of a suitableUV-absorbing ingredients into the composition. Any suitable UV-absorbingcomposition may be employed, but particularly preferred are those whichdo not impart an unpleasant color or odor to the composition, and whichdo not adversely affect the rheology of the product. Non-limitingexamples of UV-absorbing ingredients include avobenzone, cinoxate,ecamsule, menthyl anthranilate, octyl methoxycinnamate, octylsalicylate, oxybenzone, sulisobenzone, and combinations thereof.Applicants have surprisingly found that the use of such UV-absorbingingredients do not compromise the light-activated performance ofencapsulates of the present invention. Without wishing to be bound bytheory, it is believed that in many consumer product applications, e.g.,cleaning compositions including laundry detergents, shampoos and bodywashes, the UV absorbing ingredient is washed down the drain while theencapsulates of the present invention are retained in an efficaciousamount on the surface of interest where they are available to releasetheir contents on subsequent exposure to light of a sufficientwavelength. In other cleaning compositions or leave-on consumerproducts, e.g., floor cleaning compositions, drapery and upholsteryrefreshers, body lotions, and hair styling products, it is believed thatthe UV-absorbing ingredients dry down to a thin film after application,allowing the encapsulates of the present invention to sit atop or extendabove the film. This allows and efficacious amount of light of thedesired wavelength to reach the encapsulates and effect the release ofthe benefit agents.

Test Methods

LCAF Solubility Index Method:

Measuring the Miscibility of Materials in Organocompatible Silicones ViaUV-Vis % Transmittance.

The Solubility Index is determined by measuring the percentage of lighttransmittance through samples using a UV-Vis Spectrophotometer operatedin transmission mode, at 480 nm, using 1 cm path length cuvettes, inaccordance with the following procedure. Suitable instruments includethe Beckman Coulter model DU 800 UV-Vis Spectrophotometer (BeckmanCoulter Inc., Brea, Calif., USA).

All sample preparations and analyses are conducted in a laboratory withair temperature of 22° C.+/−2° C. In a glass scintillation vial combinethe predominant organocompatible silicone present in the composition,along with the material to be tested (for example, a polydimethylsiloxane polymer), at the ratio of 80:20 vol/vol. Cap the vial, and mixthe materials thoroughly for 5 minutes using a benchtop vortex mixer setto its highest speed. If two or more distinct layers of materials areclearly visible by eye in the vial after mixing, then the SolubilityIndex of the test material is considered to be indeterminate via thismethod. If distinct layers are not clearly visible by eye, then continuewith the analysis.

Turn on the spectrophotometer lamps and allow them to warm up for 30minutes prior to commencing measurements. Set the instrument to collectthe measurement in Percentage Transmission (% T) mode, at a wavelengthof 480 nm. Load all samples into 1 cm path length plastic cuvettes. Ifair bubbles are visible in the cuvettes, use a pipette to remove thebubbles, or let the bubbles settle out of the cuvette prior tomeasurement.

Zero the baseline for a neat sample of the organocompatible silicone byusing a cuvette loaded with deionized (DI) water along with a cuvetteloaded with the neat silicone. Measure the % T of the neatorganocompatible silicone. Measure the % T of the mixture oforganocompatible silicone and test sample, as prepared under theprevious instructions. Compare the % T of the mixture oforganocompatible silicone and test sample, to the % T of the neatorganomodified silicone (which was measured using a DI water blank as abaseline).

The Solubility Index is reported as a decimal number, and is calculatedas the % T of the mixture of organocompatible silicone and test sample,divided by the % T of the neat organocompatible silicone. Example;Solubility Index of Test Sample ABC:

-   =% T of ABC in Organocompatible Silicone/% T of the Organocompatible    Silicone-   =85%/98%-   =0.867    Viscosity Test Method-   Equipment: Brookfield Viscometer and AR G2 Rheometer manufactured by    TA Instruments
